時の溶融加工性に劣る。(Prior Art) Vinyl chloride resin has high transparency and is therefore used in various shapes such as building materials and automobile parts. However, vinyl chloride resins generally have a drawback of low heat resistance. In order to solve this drawback, a method has been proposed in which a chlorinated vinyl chloride resin, which has relatively high heat resistance, is used as the vinyl chloride resin. for example. Japanese Patent Publication No. 61-176650
In the publication. A composition comprising chlorinated vinyl chloride and polymethyl methacrylate is disclosed. Although the heat resistance of the precepts obtained using this composite is improved. On the other hand, it has poor melt processability when forming.

極めて悪い。A method of blending the above-mentioned chlorinated vinyl chloride resin with excellent heat resistance and vinyl chloride resin with excellent melt processability is also known. In this case, both heat resistance and melt processability are relatively improved. Since vinyl chloride resin and chlorinated vinyl chloride resin have poor compatibility, the transparency of certain shapes obtained is extremely poor.

い。JP-A-47-34836 discloses vinyl chloride resin and. A copolymer of methyl methacrylate and other (meth)acrylic esters is disclosed. As the vinyl chloride resin, at least one of polyvinyl chloride, a copolymer containing vinyl chloride in a proportion of at least 80% by weight, and a chlorinated vinyl chloride resin is used. Even in this composition, if the mixing ratio of polyvinyl chloride and chlorinated vinyl chloride resin is set at an appropriate mixing ratio, it is thought that the obtained rod-shaped body will have excellent heat resistance. However, transparency is still not sufficient.
